Hey all, this is my first post. I have a 1999 ram 3500 Cummins. I'm looking at getting some new tires and 2 inch leveling kit. I was curious of a good leveling kit and tires to run. Also will I need spacers in the rear if I go up in size? Thanks.

 

I run 235/85R16s on my 98 3500 4x4 dually. I will tell you that I originally had a set of highly squared tires on the back. While they were the "same" size, they were wider and would touch if pressure wasn't right at max load when the truck was loaded. They'd be awfully close even empty. I switched to more normal tires and they clear fine. I had already bought some 1/4" spacers, but I don't have to run them now.

Any bigger than that and you'll need spacers.

 

I don't have a dually but mine is a 3/4 ton and I run a zone offroad levelibg kit on mine it was a good price and made out of steel been on the truck for a little over a year and no problems

 

I realize this thread is a little old, but maybe this'll help the next guy who's needing the same info. I've got a '99 4x4 dually. If I remember correctly (correct me if I'm wrong) but anything larger than 245's need a spacer in the rear. And the most you can lift the front as it sits with STOCK front-end parts is 2 1/2"...otherwise you gotta replace stuff with longer parts (shocks, arms etc). I installed a 2 1/2" Rough Country (poly- like $99) block on the coil spring (be prepared with STRONG spring compressors, they are a beast!) and 2" billet rear spacers...I'm running 285's. I have to work out of it every day, so I don't want it any higher in the rear for sure, stock, plus the 285's is plenty. I do wish I could raise the front a hair more, but I'm not going to spend the money, since I'm assed up with a shot tranny and am going to have to "back in the door with my drawers down" AGAIN and spend the money for a NV 4500 complete conversion (if anyone has a donor truck with ANY of the parts needed (pedals, trans, anything) please let me know. Here's how she sits. Hope this helps someone. (I just realized my Sig says 2 1/2 billet spacers, they're 2", it won't let me edit it, Dag-Nabbit)!!!
